Upgrading of MI-8T (MT) Helicopters

TECHNICAL PROPOSALS FOR UPGRADING OF MI-8T (MT)

Modernization main tasks:

- Equipping of serial helicopter Mi-8MT with new altitude engines TV3-117VМА-SBМ-1V-03 of increased power;- Providing of day-and-night operation;- Increase of accuracy in navigation tasks solving;- Protection from MANPAD and IR guided missiles;- Upgrade of navigation and radio communication equipment for flying by local air routes;- Improvement of crew operating conditions.

REPLACEMENT OF POWER UNIT

Improvement of helicopters flying and technical performances during operation in hot climatic conditions, high-altitude take-off areas and high flight altitudesUpgrade of existing serial engine ТV3-117VМА-SBМ1:- High rate of reliability and service life- Decreasing of technical riskFurther increase of reliability and life time rates:- Life time before first repair and between repairs ................3000 hours, 3000 cycles;- Specified life...............................................................9000 hours, 9000 cycles;Growth of security for performing of single-engine flight:- Introduction of emergency (2.5 min) operation mode of the engine with 2800 h. p.- Introduction of 30-min power mode (power is equal to power during take-off mode)Improvement of economic indexes:- Decrease of operating costs by increase of life time before the first repair and between repairs;- Recovery of engines flight operability in operational conditions by replacement of main joints and modules;- Introduction of activities oriented on increase of engine operability;- Increase of limits for gas temperature allowed degradation on turbine input in the process of life time working-off;- Preservation of helicopters high flying and technical performances during installation of dust protection and exhaust infra-red suppression systems.
